The Rain Bird horizontal action impact-drive sprinkler head was recognized as a historic landmark of agricultural engineering in 1990 by the American Society of Agricultural and Biological Engineers. [3] This invention led to sprinkler irrigation development that currently exceeds 50,000,000 acres (78,000 sq mi; 200,000 km 2) worldwide.
Impact sprinkler head. An impact sprinkler (sometimes called an impulse sprinkler) is a type of irrigation sprinkler in which the sprinkler head, driven in a circular motion by the force of the outgoing water, pivots on a bearing on top of its threaded attachment nut. Invented in 1933 by Orton Englehart, it quickly found widespread use.
Were an equivalent impact predicted with a probability of 99% or more, it would rate 10 on the Torino scale. The impacts that created the Barringer Crater and the 1908 Tunguska event are both estimated to have been in the 3–10 megaton range, [13] thus, if a similar impact had been predicted with near certainty, it would correspond to Torino ...
The lower the irrigation efficiency, the higher the losses. Although reasonably high irrigation efficiencies of 70% or more (i.e., losses of 30% or less) can occur with sophisticated techniques like sprinkler irrigation and drip irrigation or by well-managed surface irrigation, in practice the losses are commonly in the order of 40% to 60% ...
Distribution uniformity or DU in irrigation is a measure of how uniformly water is applied to the area being watered, normally expressed as percentage, and not to be confused with efficiency. [1] The distribution uniformity is often calculated when performing an irrigation audit. The DU should not be confused with the coefficient of uniformity ...
The sodium adsorption ratio (SAR) is an irrigation water quality parameter used in the management of sodium-affected soils.It is an indicator of the suitability of water for use in agricultural irrigation, as determined from the concentrations of the main alkaline and earth alkaline cations present in the water.
Rainbird, colloquial name given to various birds thought to sing or come before rain, including the European green woodpecker, Jamaican lizard cuckoo, Jacobin cuckoo, Pacific koel, channel-billed cuckoo, Burchell's coucal and black-faced cuckoo-shrike, as well as certain swifts whose movements are thought to signal the coming of rain
